IMPROVEMENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. 118,658, dated August29, 1871.

To all whom it may concern:

Be it known that I, WILLIAM P. WENTwoRTH, of Seneca Falls, in the countyof Seneca and in the State of NewYork, have invented certain new anduseful Improvements in Tater-Elevators, and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the aceompanyin g drawing and to the letters of referencemarked thereon, in which drawing- Figure 1 represents my improvement inposi-l tion for use upon awell-curb; Fig. 2, a detached top-plan view ofmy device g and Figs. 3 and 4, elevations of the same from the insideand outside, respectively.

Like letters represent similar parts in each gure.

The object of my improvement is the construction of an elevator' to beused over an openv well for the raising and lowering of thewater-bucket, which shall have the advantages of simplicity, cheapness,and durability, by which, in operation, the bucket can be raisedreadily; in which there is no danger of the crank flying back orstriking the person who is turning it; and having connected with it abrake for the purpose of lowering the bucket gently into the water; andthe invention consists principally in combining with the chain-shaft anda ratchet-wheel secured thereon a crank pvoted upon said shaft andprovided with a hooked pawl, which remains pendent when said crank hangsdownward, and follows and engages with said ratchet when said crank istiuned forward, substantially as and for the purpose hereinafterspecied. It consists, further, in combining with the above-named devicesa ratehetwheel, pawl, and brake, substantially as and for the purposehereinafter shown.

In the drawing, A represents the water-elevator upon the well-curb,having a main shaft, B, suitably journaled in frames G over the centerof the well, and a wheel upon the center of the shaft, which carries thechain to which the water-bucket is attached, all of which parts, exceptthe shaft, are mentioned, in order to describe more fully the location,generalv arrangement, and method of operation of the device which is theproper subject of this application, and for no other purpose. Upon oneof the ends of the shaft B, outside of one of the frames C, the

crank D, provided with a handle, c, upon the outside, and a seat, b,upon the-inside, and cast in one piece, is loosely pivoted, so thatwhenever the hand is removed from it it hangs by its own weight in avertical position. Upon the seat b the ratchet E, provided with a claw,c, is pivoted, which claw in one direction of the turning of the crankengages with the faces of the teeth e of the ratchet-wheel F, which issecured upon said shaft. This ratchet-wheel is provided with a thimble,f, cast in one piece with it, for the purpose of giving increasedstrength, support, and stability to said wheel, and to bring its teethoutside of the frame G, and in a convenient position for the engagementof the ratchet. Upon the inside of the frame the ratchet-wheel G,provided with teeth g,is secured upon the shaft, having a body orfriction-surface, L, less in diameter than the toothed portion of saidweeel, against which frictionsmface the curved portion 'i ofthe brake H,pivoted upon said frame, passes, said curved portion being furnishedwith a proper shoe, j, and the handle of said brake being held up fromfalling by means of the strap I secured upon said frame. A pawl, J,pivoted also upon said frame, and provided with a vertical wing, It,which holds it correctly in position, engages with the teeth g of saidratchet-wheel, and prevents the same from turning.

In the operation of my device, by turning the crank in one direction theratchet E engages with its ratchet-wheel and causes the shaft to turn,which raises the water-bucket; a-t the same time the pawl J, engagingwith its proper ratchet-wheel, holds the bucket from falling back. WVhenthe hand is removed from the crank, both it and its ratchet immediatelyfall by their own ,weight into a vertical position. IVhen it is de- 1.In combination with the shaft B and ratchbrake H, substantially a-s andfor the purpose et-Whee F, the pivoted crank D, provided with shown. thehooked paWl E, which remains pendent when In testimony that I claim theforegoing I have said crank hangs downward7 and follows and hereunto setmy hand this 5th day of June, 1871. engages with said ratchet-Wheel whensaid crank is turned forward, substantially as and for the purposespeoied.
